ROOT 6.08/07 Reference Guide |
Class describing a cylindrical coordinate system based on eta (pseudorapidity) instead of z.
Class describing a 3D Cylindrical Eta coordinate system (rho, eta, phi coordinates)
The base coordinates are rho (transverse component) , eta and phi Phi is restricted to be in the range [-PI,PI)
